In the post-9/11 era, security has become omnipresent in urban centers such as New York’s financial district, often resulting in an obstructed streetscape. Finding existing street security options lacking in either performance or design, New York–based Rogers Marvel Architects developed the Turntable Vehicle Barrier (TVB), which features perforated-bronze-clad bollards set in a paved piece that can swivel to block the street or allow vehicle access as necessary.
The turntable itself is a galvanized steel frame set in a shallow foundation, allowing the system to be installed over subway tunnels, utility lines, and other pieces of urban infrastructure. The surface can be infilled with cobbles, brick, or other paving materials to match the surrounding area. “It’s a new take on an old problem, or a very typical problem that we’re all dealing with,” said juror Cristobal Correa, “and it shows an inventive solution.” Juror Jenny Wu called it “a very clever idea.” More than that, it’s secure: The TVB can stop a 15,000-pound truck traveling 50 miles per hour.
